` which the following vis a specification.

My invention relates to means for making temporary electrical connections.

It is an object of my invention to provide a, cheap, serviceable and eicient terminal having. means for making both permanent and'temporary connections. f c

My invention in its preferred form includes a wire lug terminal having a supporting portion and a socket or contact for receiving a wire, integral with or secured to said supporting portion. Projecting from one of the members, preferably the socket, is Aa projection or projectin fin for receiving a temporary connecting e ement or clip.

In the drawings, which show merely a preferred form of my inventionj Fig. 1'is a view illustrating my invention as applied to a6 meter testing switch;

Fig. 2 is an n enlarged detail perspective view of a terminal embodying my invention;

Figs. 3 and 4 are similar `views illustrating modified forms; and v Figs. 5 and 6 are enlarged detail perspective views of temporary connecting elements or clips. Y

In said drawings, 5 indicates any desired or usual switch base having'. means, such as the apertures 6, for securing the same to a support. 7, 8 indicate the usual blades of a double-pole'switch pivoted to the base at 9, 10. 11, 12 indicate contact jaws '.torv receivingA the movable blades 7 8. 13, 14 are fuses interposed between the .ma-in line 'terminals- 15, 16 and the meter terminals 17, 18. .19,20 indicate other meter terminals, and the load line terminals are indicated at 2l, 22. v 4

Switches of this class are 'usually connected with a meter and when it is desired to test the meter a temporary connectionmay be made between the main line and the load line in order that the customers service may not be interrupted while the `meter is being tested and the switch may then opened 'tov disconnect the terminals 19, 20'

from the load line terminals 21, 22.

matically a means for making temporary connections between the terminals 1T and 21, and between the terminals 18 and 22. The means for making or permitting these temporary connections constitutes the principal 23 indicates the usual supporting portion for ajwire lug terminal. Anaperture 24 may be provided therein, to receive a. screw for attaching thejbase to a support. In-

tegral with or vsecured to the portion 23 is a means for receiving a .permanent connection,

which, inthe form shown, is a socket 25, in which a wire may be secured, as bymeans of solder.v Projecting from one of the terminal parts, preferably the socket, is a fin or projection 26, of suitable size and proportions for receiving a temporary connecting element or clip. I

In the form of terminal shown in Fig. 4 the supporting portion 23 and socket 25 may be the same as corresponding elements in Fig. 2. InFig. 4, however, the fin 26 is provided with means which, in the embodiment shown, are in the -forinof one orvmore de'- pressions or grooves 27, 28, for providing a firmer hold for a temporary connecting clip, The terminal shown in Figs.-2 and 4 may be conveniently formed by casting.

In Fig. 3 is shown` a terminal which may "beinade of tubing, which is common practice is desired 'for the inished socket, and parts of the tube are crimped or bent together to form the -in or `projection 31. In the form shown the parts of the fin are not bent into conta-ct withl each other at the extreme upper edge, but contact with each other adjacent the upper edge of the socket, as at 32. rIhis construction provides means in the. form of a depression 33 at each side of the tin for more securely holding the clip in contact with the tin and preventing disengagement of the clip. j In Fig. 5 is shown a temporary spring connecting clip having jaws 34, 35 and a wire 36 connected to the clip in anyr suitable manner.

In making a temporary connection to the terminals shown in Figs. 2, 3 and 4, the aws 34, 35 of the clip are simply slipped over and engage with the projections or ns.

'In Fig. 6 is shown a clip having the jaw portions 37, 38 crossed and held in lcontact with each other by means of a spring 39, and a wire 40' is connected to the clip. In using this form of clip the outer sides are compressed and the jaws 37, 38 opened-to permit passing overthe projections or fins on t-he terminals. It vshould be understood that e the usual form ofrubber nipple or covering will be provided for the temporary connectingelips.-

The switch shown fin Fig. 1 is provided with terminals embodying my invention. When it is desired to make temporary connections, for example, to connect the termi- `nals-17 and 2l to each other. or to testing Iinstruments for example, it is necessary that terminals embodying my linvention may be used wherever temporary connections arevarious changes vand `modifications may be made, all Within the scope of the appended claims. Y.

I claim:

1. AV one-piece Wire lugterminal, com-v prising a perforated supporting portion, a

wire receiving socket member, and a iin contact projecting therefrom, said fin contact being adapted to receive temporary electrical connection and having a depression therein for receiving .said temporary electrical connection. Y

2. A one-piece WireV lug terminal, comprising a Hat supporting portion having means for connecting *saidv supporting por-v tion to a support, an integral tubular socket extending from saidsupporting portion for receiving a Wire and making a permanent connection, and an integral contact lin project-ing from said tubular socket for receiving a temporary connecting cl1p. .f
